Increased importance of cool‐water fish at high latitudes emerges from individual‐level responses to warming
Abstract High latitude ecosystems are experiencing the most rapid warming on earth, expected to trigger a diverse array of ecological responses. Climate warming affects the ecophysiology of fish, and fish close to the cold end of their thermal distribution are expected to increase somatic growth fro...
